Similarities and differences in the lifestyles of populations using mode 3 technology in North Africa and the south of the Iberian Peninsula

In the geohistorical region of the Strait of Gibraltar, which includes the south of the Iberian Peninsula and North Africa, important research has been carried out in recent years. This research has allowed us to document the presence of human groups as early as the Middle Pleistocene. Classical anthropology refers to these groups using various terms Homo Neanderthalensis in the south of Europe and Homo sapiens sapiens in North Africa). The current records exhibit important similarities concerning lithic technology (the so-called ‘Mode 3’, ‘Mousterian’ or ‘Middle Stone Age’), and the exploitation of marine resources. From an anthropological or cultural perspective, both groups were hunter-gatherers with similar lifestyles. Bearing these similarities in mind, three hypotheses are here presented

New fossils from Jebel Irhoud, Morocco and the pan-African origin of Homo sapiens

Fossil evidence points to an African origin of Homo sapiens from a group called either H. heidelbergensis or H. rhodesiensis. However, the exact place and time of emergence of H. sapiens remain obscure because the fossil record is scarce and the chronological age of many key specimens remains uncertain. In particular, it is unclear whether the present day ‘modern’ morphology rapidly emerged approximately 200 thousand years ago (ka) among earlier representatives of H. sapiens1 or evolved gradually over the last 400 thousand years2. Here we report newly discovered human fossils from Jebel Irhoud, Morocco, and interpret the affinities of the hominins from this site with other archaic and recent human groups. We identified a mosaic of features including facial, mandibular and dental morphology that aligns the Jebel Irhoud material with early or recent anatomically modern humans and more primitive neurocranial and endocranial morphology. In combination with an age of 315?±?34 thousand years (as determined by thermoluminescence dating)3, this evidence makes Jebel Irhoud the oldest and richest African Middle Stone Age hominin site that documents early stages of the H. sapiens clade in which key features of modern morphology were established. Furthermore, it shows that the evolutionary processes behind the emergence of H. sapiens involved the whole African continent
